Even if everything was working (unable to tell from the log snippet), using a hostname to map to 127.0.0.1 won't work with current versions of CUPS - DNS rebinding attacks often bind a name to point to the loopback interface, so we only allow "localhost" for 127.0.0.1. There is no way to turn off this security protection.
